l SPECIFICATION forming' part of Letters Patent N0. 677 ,949, dated July 9, 1901.

Application iled June 6, 1900. Serial No. 19,310. (No model.) A

T all whom t may concern:

Be it known that LWILLIAM B. CUTHBERT- SON, a citizen of the United States, residing at New Brighton, Beaver county, State of Pennsylvania, have invented certain new and useful Improvements in Motors, of which the following is a specication.

My invention relates to motors; and it consists in means whereby to secure a practically continuous motor Huid-pressure; and to this end my invention consists in the combination, with a motor, of a casing having a pressure-chamber in which pressure is created and maintained by the explosion of a succession of charges of explosive mixture, as fully set forth hereinafter and as illustrated in the accompanying drawings, in which.-

Figure l is a sectional elevation on line m with the casing removed and on line .c z of Fig. 2 of an apparatus embodying myimprovement; Fig. 2, a transverse sectional plan; Fig. 3,`an edge View, and Fig. 4 a section illustrating a modification.

The casing A is of any suitable character and is mounted upon a suitable base and contains a pressure-chamber N, which communicates with a suitable motor G.' This motor may be any suitable turbine; but, as shown, it is a turbine having a member with fixed blades and a rotative member carrying other.

blades, as in ordinary turbines, the rotative member being mounted upon a shaft O, turn-V ing in suitable bearings of the casing.

Within the pressure-chamber N'is arranged a series of barrels D, open at `theopposite ends, and preferably each barrel is surround-5 ed by a water-jacket W, Fig. 4:, as shown. Water lis maintained in circulation through these jackets in order to prevent the over,- heating of the barrels. Y

A disk B, which rotates with its inclined periphery in as close proximity as possibleV to an annular inclined face of the casing A, constitutes a breech for the barrels D, closing the outer endsof the latter. The inner ends of the barrels are closed by a disk F, and in this disk F are openings M, which are brought opposite the inner ends of the barrels at the moment when the charge in the latter is exploded.

Any suitable means is provided whereby the barrels are supplied (in succession, pref-v erably) with an explosive mixture and wherea by the explosive mixture after being introduced is exploded, the result of the explosions (preferably in rapid succession) being v multaneously opposite a port J in the casing- A, which port communicates with a pipe leading to a supply of gaseous mixture under pressure. B y this arrangement as the channel j is brought opposite a barrel D and a port J the gaseous mixture under pressure will flow from .that port J through the channel j and into the barrelD. The end of the channel j opposite the barrel D is elongated or curved, so as to remain in communication with the barrel during the rotation of the disk B until the barrel is filled, when the passage ofthe channel opposite the port J will cut off the supply and bring the fiat face of the disk B opposite the end ,of the barrel lD. In the disk B, following the channel j,

is another channel. h, also having an elon-V gated inner end and which as it is brought opposite .the barrel D is alsonbrought into communication with an outlet-port H, there being an outlet-port for each barrel, so that after the explosion of the lbarrel D the products of combustion, if any, which have not escaped intoV the chamber N may have a free access to the channel h and port H. Each opening M in the ring or disk Fis so arranged that it is brought opposite the inner end of a barrel D, and the charge in the latter is exploded, so that the gases iiowing from the barrel will pass directly to the chamber N; The explosion of the charge in the barrel D is then followed by the closing` of' the latter by the plane portion of the disk or ring F.

Any suitable means may be employed for igniting the charge in the barrel D. For in IOO stance, in the plane portion of the breechdisk B between the channelsj and h is an opening y, and outside of the disk B is mounted a ame-igniter K on the disk in such position that as the opening fJ is brought opposite the barrel the gas passing through the opening will be projected against the flame and ignited, and the charge in the barrel will be exploded just as the opening y passes beyond the barrel.

I have illustrated the flame-igniter as one means only whereby the explosion may be effected; but an electrical ignitcr or any other means of igniting the charge may be employed.

I have described the operations only in connection with one of the barrels; but the same operation takes place for each barrel in turn, and it will also be evident that any suitable number of barrels maybe arranged symmetrically at equal distances within the casing A, with supply and exhaust ports in the casing A for each barrel, and that by increasing the number of barrels I may secure a series of explosions of comparatively small charges, and thereby the development of a continuous pressure for operating the motor, which is preferable to exploding at greater intervals larger charges.

The cycle of operations may be recapitulated as follows: The barrels D being stationary and the disks B and F revolving with the shaft, while the inner end of a barrel D is closed by disk F, a charge of explosive mixture is admitted to that barrel from its adjacent port .I in the casing A through the channelj in disk B, which channel establishes communication between that particular port J and that particular barrel. Upon disk B revolving further, communication between port .I and the barrel is cut oif, and the opening y in the disk B next comes opposite the outer end of the barrel. Since there is a iiame-igniter mounted on the disk immediately adjacent to the opening y, the gases tending to escape through that opening are thereby ignited and the charge is exploded just as the opening Q/ passes beyond the barrel. The gases flowing from the barrel will pass directly to the pressure-chamber N through an opening M in the disk F, which opening is timed to uncover the inner end of the barrel just at the time of explosion. Upon further rotation of disk B a channel h in the disk is brought opposite the barrel D and an adjacent exhaust-portH in the casing, communication thus being established between the barrel and the exhaust-port, so that any products of combustion remaining in the barrel which have not passed into the pressurechamber N may escape. Before communication is established between a barrel and its exhaust-port in the casing the inner end of the barrel is closed by a solid portion of disk F. This same cycle of operations of charging a barrel, igniting the charge, admission of the gases to the pressure-chamber N, and the exhausting of any products of combustion remaining in the barrel takes place for each barrel one after another, one barrel only at a time being in operation.

While I have illustrated the apparatus, Figs. 1 and 2, as provided'with a shaft carrying the disks B and F, it will be evident that the disks B and F may be stationary and that the barrels D may be secured to arms and carried by the shaft C with precisely the same effect as above and as illustrated in Fig. 4i.

Without limiting myself to the precise construction and arrangement of parts shown, I claim as my invention- 1. The combination of a casing containing an annular pressure-chamber, a turbine motor arranged within said pressure-chamber, to receive the gases therefrom and to be thereby propelled, a series of barrels arranged adjacent to the periphery of the pressure-chamber, means for supplying charges of explosive mixture to and igniting the same successively in said barrels, and means for discharging the barrels successively into the pressure-chamber, substantially as described.
